The franklinite formula, (Zn^5Mn0 33Fe017Mg0 J (Fe179Al0(9)O4) is consistent with the average composi- tion of Sterling Hill concentrates reported by Frondel and Klein (1965). In the course of the quantitative analyses some of the pseudomorphs were observed to be multiphase. Most of the additional minerals present were identified using the energy-dispersive system. The back-scattered elec- tron image (Figure 3) shows that about half of the sharply defined pseudomorph is dinochrysotile (appears as dark gray and has a crackled appearance). The rest is barite (appears as white) and manganoan calcite (appears as medium gray). Careful inspection of the calcite field reveals patches of a second calcite (appears as a paler gray in image) which has a higher manganese content. On the left edge of the smaller barite field is a gray manganese- magnesium silicate (indicated as #6 in Figure 3) that may be sonolite. The elongated mineral with the ragged out- line in the dinochrysotile field was not identified.

Discussion This study clearly established that the modified octahedrons occurring as abundant inclusions in the franklinite of sample HI 13721 are pseudomorphs pre- dominantly composed of clinochrysotile. No determina- tion of the antecedent mineral is yet possible as no rema- nent isotropic core has been found within the pseudo- morphs. The best clue to its identity is its morphology. The modified octahedral morphology of these pseudo- morphs is the typical habit of spinal-group minerals. 1 suggest that the antecedent was a member of the spinel group, perhaps gahnite. Exsolution intergrowths of gahnite in franklinite are described by Frondel and Klein (1965) and Carvalho and Sclar (1988). The accom- panying forsterite contains exsolved willemite (Francis, Figure 1 (Top).

If the franklinite originally crystallized with "excess" aluminum and magnesium, it is likely that it would have exsolved a separate aluminous spinel-group mineral, gahnite. The gahnite was later replaced by clino- chrysotile etc. providing microscopic evidence for a geo- logical event that is not at all obvious in a megascopic examination of the hand sample.

The age determination for the orebody, was made by Dr. G. J. Wasserburg, California Institute of Technol- ogy, vising lead isotope methods on uraninite. The age, 955 million years, plus or minus 30 million years, was reported by Frondel (1970).

The Buckwheat Dump Uraninites During the autumn of 1989 a discovery of uraninite was made on the Buckwheat Dump at • Franklin. This material is unlike the Sterling Hill uraninite in several ways. First of all, it was found *-**«* in a calc-silicate (skarn) matrix. The associated minerals are: a gray feldspar; a greenish-black pyroxene; an altered, granular, brownish garnet; extremely sparse willemite; and a member of the allanite Figure 5 (lower left).
